Procedure
A mixture of 3-(4-nitro-phenyl)-1-phenyl-prop-2-en-1-one (24.9 g, 98.3 mmol), Raney nickel (7.0 g), MeOH (100 mL), and THF (400 mL) was shaken in a hydrogen atmosphere of 51 psi at 20° C. for 18.5 hours. The catalyst was filtered, and the filtrate was concentrated. The residue was recrystallized from 95% EtOH, to give the title compound, m.p. 76°-78° C. 1H NMR (CDCl3) δ 2.98 (t, 2 H), 3.25 (t, 2 H), 3.62 (bs, 2 H), 6.65 (d, 2 H), 7.05 (d, 2 H), 7.40-7.61 (m, 3 H), 7.96 (d, 2 H).
